Question 1
A CMOS inverter operates with a 1.8V supply and drives a load of 150 fF. If it switches at 15 MHz with an activity factor of 1, calculate the dynamic power dissipation.
💡 Hint: Apply the formula carefully with the given values.
Question 2
Discuss how you would optimize a CMOS inverter to reduce both static and dynamic power dissipation without compromising performance.
💡 Hint: Consider methods that align with design principles in modern VLSI.
